Definitions

  • the present invention relates to a winding method, particularly a method of producing a coil of fine wire on a core, on which is mounted at least one electronic component comprising at least two metal tracks to be connected at the two ends of the coil.
  • the coil in question here is produced using a wire of small diameter, generally between approximately 0.020 mm and approximately 0.12 mm on enamelled insulation and the electronic component typically has dimensions of the order of 1 mm x 1 mm with a thickness of approximately 0.5 mm, the metal tracks to be connected having dimensions of a few tenths of mm.
  • the diameter of the core is here of the order of 10 to 50 mm, for a length of coil, a non-critical value, which can be from a few mm to about ten mm.
  • the invention also relates to the core which can be wound by this method.
  • an electronic component is connected to a coil, which then acts as a tuned antenna for a certain response frequency.
  • the electronic component is rigidly fixed to the core of the coil.
  • very sophisticated means must generally be provided to bring the two ends of the coil wire exactly opposite said metal tracks to fix them there, preferably by welding.
  • guide means of the wire generally mobile, in order to bring it, when it is unwound from the winding head, in position to be fixed on the metal tracks.
  • EP-A-0.432.239 describes a method of winding a core provided with two metal tracks to be connected at the two ends of the coil.
  • the wire is guided by mobile guide means, some of them being arranged on the rotary table holding the cores to be wound, while others depend on the movement of the Flyer responsible for winding the wire.
  • a method of winding a coil core provided with an electronic component according to the preamble of claim 1, as well as a coil core provided with an electronic component according to the preamble of claim 3 are also described in EP- A-0.405.671.
  • the wires connecting the coil to the component follow two parallel paths oriented along the longitudinal axis of the coil.
  • the winding process described in this document is relatively complex and although the means necessary for this purpose are not described, the person skilled in the art understands that the winding head must be capable of carrying out winding along the longitudinal axis. of the core and that either the winding head itself or fairly sophisticated guide means must be able to make wire attachments, by winding the latter around fasteners, this along radial axes perpendicular to the longitudinal axis.
  • An object of the present invention is therefore to propose a method of winding a core supporting an electronic component, by which the input and output wires of the coil are suitably guided to pass over the metal tracks of the electronic component. , this by simple guiding means, that is to say fixed, using a winding head performing only simple movements and not requiring high course accuracy.
  • Another object of the invention is to provide a core supporting an electronic component which can be wound by the above method, this core which can be obtained by simple manufacturing methods, as well as a transponder equipped with such a core.
  • the invention provides a winding method according to claims 1 to 2, a coil core having the characteristics of claims 3 to 10, as well as a transponder according to claim 11.
  • a winding machine 1 comprising in particular a rotary table 10 whose periphery is provided with a plurality of attachment points 11 of coil cores 2.
  • the attachment points 11 may for example be each consisting of a portion of rod projecting radially relative to the periphery of the rotary table 10, these portions of rods comprising means making it possible to orient all the cores 2 in the same way around their longitudinal axis, for example, and at case where the rod portions are of circular section, by providing them with a flat so as to adapt to the shape of a longitudinal hole passing through the core (see FIG. 4). Any other means making it possible to hold and orient all the cores 2 on the rotary table 10 at the same angle can obviously be used.
  • the method and the core according to the invention also adapt when the winding machine 1 does not include the rotary table 10, but where all the cores 2 are arranged side by side on a slender element; in this case the relative movements between the cores 2 and the winding head 12 described below will be adapted accordingly.
  • the winding machine 1 therefore comprises a winding head 12, preferably of the flyer type, comprising in particular a wire-carrying coil 12A as well as a wire conducting arm 12B comprising drive means (not shown), making it possible to impose a rotational movement on it around a radial axis relative to the rotary table 10, to block it according to several angular positions determined around this axis, as well as to impose translational movements as well as stops along said axis. As shown in FIG.
  • the rotary table 10 successively has a core 2 to be wound in front of the head 12, the winding wire 3 passing from an already wound core to the core to be wound, led by the driving arm 12B and guided by guide means which will be described below, passing over the first metal track of the electronic component, carrying out the winding, passing over the second metal track and then being led to the next core to be wound.
  • a winding machine is generally supplemented with means (not shown) enabling the wires to be welded to the metal tracks of the electronic components. After the welds of the two end wires of a coil have been made, other means (not shown) cut or tear off the portions of wires connecting two successive coils in order to separate them.
  • mobile guide means forming part of the rotary table 10 and / or arranged near the winding head 12, are responsible for conducting the wire 3 so that it passes exactly over the metal tracks; these guide means are generally mobile and therefore expensive and delicate.
  • complementary means of guide 13 can be provided on the rotary table 10.
  • FIG. 2 shows a first embodiment of a coil core 2 according to the invention making it possible to overcome the mobile guide means of the prior art mentioned above.
  • This core is preferably made of synthetic material, preferably obtained in one piece by injection, of generally cylindrical shape, comprising an end part 20 and a winding part 21, these two parts being generally of circular section.
  • the coil also preferably comprises cheeks 22A, 22B and 22C which respectively separate the parts 20 and 21 and limit the other ends of the winding parts 21 and of end 20.
  • a housing 23 is provided on a portion of the periphery of the part end 20, in order to precisely accommodate the electronic component 4. It is composed of an encapsulated circuit 40 provided on one of its faces with two metal tracks 41 and 42 intended to be connected to the ends of the wire constituting the coil 30.
  • the depth of the housing 23 is such that the metal tracks 41 and 42 are just flush with or protrude from the envelope cylindrical constituting the end portion 20 (see Figure 4).
  • the end part 20 comprises its own guide means, making it possible to guide the wire 3 and bring it above said metal tracks.
  • These guide means consist, imagining that the wire 3 is brought from above in FIG.
  • a second lateral guide means 25B so that, when the wire 3 is stretched between the lateral guide means 24B and 25B, when making the coil 30, the wire 3 is brought directly above the metal track 41 in a manner which will be described in more detail later.
  • the wire 3 is brought by the wire conducting arm 12B on the other side of the first input guide pad 24A, then along the lateral guide means 24C and 25C and finally on the output guide pad 25A, from where, being tensioned again, it is automatically positioned directly above the metal track 42 as before.
  • the guide edges of the lateral guide means 24B and 25B are aligned with respect to the metal track 41, while those of the guide means 24C and 25C are aligned with the metal track 42
  • the lateral guide means 24B, 25B, 24C and 25C consist of bulges of the cheeks 22A and 22C, the exact shape of which will be described below.
  • Figure 3 shows another embodiment of a coil core 2 according to the invention.
  • This embodiment is particularly suitable in case where the cheek 22C limiting the end of the end part 20 of the core is not necessary.
  • the lateral guide means 24C and 25C, as well as possibly also those noted 24B and 25B, consist of pins whose exact shape is described below.
  • FIG. 5 The forms according to vertical section planes mutually perpendicular to the above guide means are shown in Figures 4 and 5.
  • the lateral guide means 24B and 24C consisting of bulges of the cheeks 22A and 22C , these bulges comprising a first upper part of semi-conical shape superimposed on a lower part of semi-cylindrical shape.
  • the input guide pad 24A also composed of a conical upper part and a cylindrical lower part.
  • the wire 3 is led to the bottom of said successive V-shaped notches and from there on the cylindrical parts constituting the lower portions of the guide means 24A and 24B as well as 25A and 25B.
  • the cylindrical faces of the lower portions of the lateral guide means 24B and 25B are arranged so that when the wire 3 is stretched between them, it is placed exactly in line with the metal track 41.
  • Figure 4 is a section along the line IV-IV of Figure 2, where we see the wire 3, kept taut from the previous core, which was brought behind the input guide means 24A, in front of the lateral guide means 24B and 25B, then taken through the passage notch 26A, which had the effect of stretching the wire 3 and passing it from the conical upper parts of the guide means to the lower parts cylindrical in order to bring it down to the level of the metal track 41.
  • the wire 3 will pass from the winding part 21 to the end part 20 through the passage notch 26B and will be led in front the inlet guide means 24A, the lateral guide means 24C and 25C then in front of the outlet guide means 25A (see FIGS.
  • Figure 4 clearly shows the general shape of the guide means, composed of a conical upper portion ( Figure 3) or semi-conical ( Figure 2) and a lower portion respectively cylindrical or semi-cylindrical. It can be seen that these guide means are generally projecting from the cylindrical surface of the end portion 20, preferably being parallel to each other.
  • the inlet guide means 24A is of circular section while the outlet guide means 25A is of oval section or having the shape of a convex lens.
  • the inlet and outlet means are preferably of the same shape, whether it is one or the other.
  • FIG. 4 also shows the central hole 27 provided with the positioning flat 27A indicated above.
  • the core 2 is preferably obtained by injection of a synthetic material, the guide means 24A, 24B, 24C, 25A, 25B and 25C as well as the housing 23 being directly obtained during this manufacturing operation; as a variant, it is also possible that for the guide pads, some of them consist of elements added to the core 2.
  • FIG. 6 shows an embodiment of the core 2 comprising two successive housings 23 in order to have two components side by side 4 comprising metal tracks to be connected together and with the winding.
  • These two components can be either two components comprising identical circuits, either two components comprising different circuits or it may be a component comprising a circuit and a passive element such as a resistor or a capacitor.
  • the constraints are that the housings 23 have a shape adapted to receive these components and that each of them comprises two metal tracks which are aligned two by two on the end part 20 of the core. We can also have more than two components with the same constraints as above.
  • the ends of the wires can be cut or torn off below the first track and in beyond the second, preferably by automatic means forming part of the winding machine. It is necessary to ensure that the wires are pulled out so that the other end of the wire is already welded to a metal track of the component placed on the next core in order to keep the wire stretched for the winding operation described above.
  • Each component 4 is held at the bottom of its housing 23 by the ends of the wires which press it from two opposite sides against this housing bottom; this type of support is generally sufficient given the very low mass of the component. If, however, this retention is not sufficient, for example for devices subjected to sudden movements, additional holding means can be provided, for example a drop of glue placed at the bottom of the housing 23, or else mechanical holding means , or it is also possible to encapsulate the component on the core by covering it for example with a material melting at low temperature and adhering to the portions of the cylindrical surface of the end portion 20 close to the housing 23. Such a encapsulation is generally not necessary for a core comprising a cheek 22C limiting the end part 20, this cheek offering sufficient mechanical protection to the component.
  • the core 2 according to the invention is directly provided with means for guiding the winding wire 3, making it possible to pass the wire directly over the metal tracks of the electronic component or components, these guide means comprising inclined surface portions and rectilinear surface portions so that the wire gradually approaches the metal track on which it is to be welded, under the effect of a tension which is exerted on it or under the effect of pressure applied to it by the welding tips.
  • such a core makes it possible to carry out a winding on a winding machine comprising no movable guide means for the wire, possibly even under certain conditions comprising no guide means, these being transferred to the core.
  • This makes it possible to work with relatively simple winding machines, the movement control of the Flyer is also relatively simple since the latter only rotates in one direction and since its longitudinal movement control may not require great precision of positioning.
  • the additional cost of the injection mold caused by the need to provide the guide means on the core is largely offset, given the high number of cores produced, by the savings made on each winding machine.
  • Another advantage of the method and of the core according to the invention is that the guide means cannot be adjusted since they are fixed and integrated into the core.
